Highlighting RTT issues to which no obvious solution may be available - (Clauses 13.7 and 13.8 of TR 103 708)
Clauses 13.7 and 13.8 of TR 103 708 highlight the following issues:
13.7 Awareness versus distraction
The variety of things that potentially need to be signalled to users to ensure that everyone is able to effectively participate, including everything referred to in the previous clauses, could potentially be overwhelming to some users who suffer from attentional issues. Some users might find themselves getting too focused on the notifications and find that it is distracting them from following the content of the discussions. Others may simply get overwhelmed by the frequency and variety of status information being directed at them and have a total attentional overload and be unable to continue participating.
There is no simple solution that will provide every user exactly what they want to be aware of and nothing more in the exact way that meets their individual needs. The only likely resolution to this dilemma will be a high degree of personalization to individual users. But a further dilemma is that the wider the scope of personalisation that is made available to users the more scope there is for having the user interface to personalize the user experience being a significant complicating factor.
As EN 301 549 [i.13] will never contain complete detailed user interface solutions, it is as yet unclear to what extent it will be possible to alert and guide those who provide the user interfaces to pay attention to trying to find the right balance between ultimate configurability and simplicity.
13.8 Programmatic determinability of the new notifications
Most of the examples in the present document are expressed in terms of providing text content and notifications in terms of their visual appearance on screens. Although this should be generally covered by other requirements in EN 301 549 [i.13], the availability of this information to all users, including Deaf-Blind users, should be implicit in all the new requirements added to the standard. This might sometimes be emphasised by strategically placed notes that remind developers of the obligation for the content and notifications to be available in an accessible way to all users.
